Florence Welch and Jack Penate are amongst the musicians who have shared the message on Twitter, in order to help find Connolly. A police report with a description has been released, which reads:

Police are growing increasingly concerned for a man who is missing... Adam is described as white, with short black hair, approximately 5' 8", medium build, with a small tattoo of two triangles on his right elbow region, a small tattoo of a crescent on left forearm, a short black moustache and stubble.

It continues: "He was last seen wearing blue suede trainers, a black bomber jacket and dark jeans. He was also carrying a black shoulder bag. He was riding a vintage 'Roberts' bike described as pistachio green with short black straight handlebars and with a wooden mud flap on the rear."

"Anyone who has seen Adam or anyone who knows of his whereabouts, or who has seen the bike should call 020 8271 7756 or - in an emergency - 999."
